So after 1500 miles on rough michigan roads and absolutely no problems with my Pure fix I had a flat tire. I thought it would be a mounting problem or something, when I took it apart I can see that tube protecting strip is actually too thin and there is no way to get it so it will cover all the spoke holes in the rim. They need to put a thicker one in. I changed it to a wider one myself. What a piece of junk lol Anyway I have had 1500 miles of Pure Fun and intend to have another 1500 of problem free riding.
